WebWe show analytically and empirically that this simple scheme works well. When the network demand spikes beyond provisioned capacity, Aequitas achieves a latency SLO that is 3.8× lower than the state-of-art congestion control at the 99.9 th-p and admits up to 2× more PC RPCs meeting SLO when compared with pFabric, Qjump, D 3, PDQ, and WebA congestion control protocol that can alleviate these problems of PFC is needed. We propose a protocol, called P4QCN for this purpose. P4QCN is a congestion control scheme for RoCE and it is an improved Quantized Congestion Notiﬁcation (QCN) design based on P4, which is a ﬂow-level, rate-based congestion control mechanism.
